Indeed, these tiny structures inside our cells are important beyond imagining. Without mitochondria, we would have no cell suicide, no sculpting of embryonic shape, no sexes, no menopause, no aging.In this fascinating and thought-provoking book, Nick Lane brings together the latest research in this exciting field to show how our growing insight into mitochondria has shed light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. These findings are of fundamental importance, both in understanding life on Earth, but also in controlling our own illnesses, and delaying our degeneration and death. Readers learn that two billion years ago, mitochondria were probably bacteria living independent lives and that their capture within larger cells was a turning point in the evolution of life, enabling the development of complex organisms. Lane describes how mitochondria have their own DNA and that its genes mutate much faster than those in the nucleus. This high mutation rate lies behind our aging and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer. We also discover that mitochondrial DNA is passed down almost exclusively via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to "Mitochondrial Eve," giving us vital information about our evolutionary history.Written by Nick Lane, a rising star in popular science, Power, Sex, Suicide is the first book for general readers on the nature and function of these tiny, yet fascinating structures.

    The Big Bang. DNA. Natural selection. All are ideas that have revolutionized science—and all were dismissed out of hand when they first ap­peared. The surprises haven’t stopped in recent years, and in At the Edge of Uncertainty, bestselling author Michael Brooks investigates the new wave of radical insights that are shaping the future of scientific discovery.   Brooks takes us to the extreme frontiers of what we understand about the world. He journeys from the observations that might rewrite our story of how the cosmos came to be, through the novel biology behind our will to live, and on to the physi­ological root of consciousness. Along the way, he examines how it’s time to redress the gender im­balance in clinical trials, explores how merging hu­mans with other species might provide a solution to the shortage of organ donors, and finds out whether the universe really is like a computer or if the flow of time is a mere illusion.

    In the intervening period, many species of early ape and human have lived and died out, leaving behind the fossilized remains that have helped to make the detailed picture of our evolution revealed here.This exciting, up-to-the-minute account is divided into three accessible sections. "In Search of Our Ancestors" examines the contexts in which fossilized remains have been found and the techniques used to study them. "The Fossil Evidence" traces in detail the evolution of apes and humans, from Proconsul to the australopithecines, and Homo erectus to the Neanderthals and Homo sapiens. The latest fossil finds at major new sites such as Dmanisi in Georgia and Gran Dolina in Spain are appraised, and new advances in genetic studies, including the extraction of DNA from extinct human species, are evaluated. "Interpreting the Evidence" reconstructs and explains the evolution of human behavior, describing the development of tool use, the flourishing of the earliest artists, and the spread of modern humans to all corners of the world. The book is superbly illustrated with hundreds of photographs, diagrams, and specially commissioned reconstruction drawings by the artist John Sibbick.

    The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.

    Why We Get Sick compels readers to reexamine the age-old attitudes toward sickness. Line drawings.

    But we long to know more: how did these animals actually behave? We are fascinated by the daily lives of our fellow creatures--how they reproduce and raise their young, how they hunt their prey or elude their predators, and more. What would it be like to see prehistoric animals as they lived and breathed?From dinosaurs fighting to their deaths to elephant-sized burrowing ground sloths, this book takes readers on a global journey deep into the earth's past. Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals. Dean R. Lomax examines the extraordinary direct evidence of fossils captured in the midst of everyday action, such as dinosaurs sitting on their eggs like birds, Jurassic flies preserved while mating, a T. rex infected by parasites. Each fossil, he reveals, tells a unique story about prehistoric life. Many recall behaviors typical of animals familiar to us today, evoking the chain of evolution that links all living things to their distant ancestors. Locked in Time allows us to see that fossils are not just inanimate objects: they can record the life stories of creatures as fully alive as any today. Striking and scientifically rigorous illustrations by renowned paleoartist Bob Nicholls bring these breathtaking moments to life.

    As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species.

    Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible.Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow.The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.

    It is intended to demystify ecological models and the mathematics behind them by deriving the models from first principles. The Primer explains in detail basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation, island biogeography, and, in a chapter new to this edition, succession. The book may be used as a self-teaching tutorial by students, as a primary textbook, or as a supplemental text to a general ecology textbook.

    Laufer exposes the network of hunters, traders, breeders, and customers who constitute this nefarious business—which, estimated at $10 to $20 billion annually, competes with illegal drug and weapons trafficking in the money it earns criminals.

    For almost a century they defied classification; they outwitted hunters and escaped trappers, left the public elbowing and zoo turnstiles spinning, were sent on diplomatic journeys, branded onto products and turned into company logos. Thanks to the World Wide Fund for Nature this species became the face of global conservation. Yet in spite of humankind’s evident obsession with the giant panda, it is only in the last few decades that scientific research has begun to show us what this mysterious, frequently misunderstood creature is really like.Henry Nicholls uses the rich and curious history of the giant panda to do several things: to ponder our changing attitudes towards the natural world; to offer a compelling history of the conservation movement; and to chart the rise of modern China on its journey to become the self-sufficient, twenty-first-century superpower it is today.

    Each chapter will review key terms, test for understanding basic concepts, and pose research-based problems. The Problems Book has been designed to correspond with the first twenty chapters of Molecular Biology of the Cell, Fifth Edition.Includes the solutions to the end-of-chapter problems in the textbook Molecular Biology of the Cell, Fifth Edition. Contains over 2,000 problems and their solutions. All of the solutions to the problems in The Problems Book are on the CD-ROM that is packaged with every copy of the book. The problems are organized into the following categories: Terms to Learn, Definitions, True/False, Thought Problems, Calculations, and Data Handling.The Problems Book will be useful for homework assignments and as a basis for class discussion. It could even provide inspiration for exam questions.

    James Cleaves II seek to answer the most crucial question in science: How did life begin? They trace the trials and triumphs of the iconoclastic scientists who have sought to solve the mystery, from Darwin’s theory of evolution to Crick and Watson’s unveiling of DNA. This fascinating exploration not only examines the origin-of-life question, but also interrogates the very nature of scientific discovery and objectivity.

    From the first microbes and jawless fishes that evolved into the myriad species we know today-sharks, whales, dolphins, and, of course, humans-Ellis reveals the deep evolutionary mysteries of the sea. Encyclopedic in scope and complemented by more than sixty drawings, Aquagenesis is a fascinating work that will astonish readers with the wonder, richness, and complexity of the evolution of life. "Quite simply, the best account we now have of the origins of human life." (Te Christian Science Monitor)
